Floor tile system for mounting vehicle seats and methods for mounting vehicle seats

ABSTRACT

A mounting tile for mounting a vehicle seat to a vehicle floor comprises at least two tubular members having a rectangular cross-sectional shape and a U-shaped channel having apertures that may include weld nuts for receiving fastener elements protruding from the bottom of the vehicle seat structure. A method for mounting a vehicle seat using the mounting tile includes affixing angle iron to the side edges of the floor, affixing a layer of metal plating on top of the angle iron, affixing one or more mounting tiles to the metal plating, positioning filler material between the one or more mounting tiles, positioning a floor covering over the mounting tiles and filler material, aligning the fastener elements of the vehicle seat structure with apertures in the mounting tile, and attaching the fastener elements and the seat to the mounting tile.

FIELD OF THE DISCLOSURE

The present invention relates generally to a mounting tile system for mounting vehicle seats to the floor of a vehicle, to enable a customized fixed configuration or one-time reconfiguration of the arrangement of seats in the vehicle, as well as to methods for mounting vehicle seats using the mounting tile apparatus.

BACKGROUND OF RELATED ART

Small delivery trucks and other commercial vehicles and vans are sold by the original equipment manufacturer (OEM) with completed vehicle floors, sometimes having pre-installed seats. However, certain vehicle owners desire to customize their vehicle and configure or reconfigure the seating arrangement therein for specific purposes. For example, one vehicle owner may wish to configure the seats in a vehicle, such as a van, to enable the van to safely transport both passengers and cargo. In another example, a vehicle owner may wish to remove the original seats and reconfigure the arrangement of seats to enable the vehicle to safely transport a passenger confined to a mobility device, such as a wheelchair or motorized scooter.

A key consideration for vehicle conversion is that vehicle seats must meet the National Highway Traffic Safety Administration's Federal Motor Vehicle Safety Standards (FMVSS) and Regulations. According to the National Highway Traffic Safety Administration, the FMVSS relevant to seating systems establishes requirements for seats, attachment assemblies and installation, to minimize the chances of failure due to forces acting on seats in the case of vehicle impact. As such, in any vehicle conversion in which seats are installed or removed and re-configured, the seats must meet the requirements set by the FMVSS.

To reconfigure a vehicle's seating arrangement, it is known in the vehicle conversion business to remove the various layers of flooring installed by the original equipment manufacturer down to the vehicle's true “floor,” which typically comprises an uneven metallic surface, referred to herein as “the OEM floor,” as shown at reference numeral 101 in FIG. 1. At that point, the vehicle converter can rebuild various layers on top of OEM floor 101 to enable the mounting of seats in the new configuration.

In one example, it is known that the vehicle floor atop the OEM floor can be replaced, in part, with a series of tracks traveling parallel to the longitudinal axis of the vehicle, wherein the tracks are capable of receiving and securing fastener elements protruding from the bottom of the replacement seats. Using these tracks, a vehicle owner can restrainably move and relocate an installed seat forwards or backwards, parallel to the longitudinal axis of the vehicle, to enable the seats to be securely positioned closer or farther to the front of the vehicle, typically, in full compliance with FMVSS. Such track assemblies provide a specific benefit to the vehicle owner: the ability to move the seats forward or backward, or side-to-side, from one point in the track to another point, as desired, to reconfigure the seating arrangement quickly and easily, without the aid of a conversion technician. However, the flexibility provided by these track assemblies also comes with certain drawbacks. For example, the track assemblies are expensive and complicated to install—and these drawbacks only need be endured if the vehicle owner requires that the vehicle seat configuration remain flexible and repositionable without taking the vehicle out of service. For vehicle owners who prefer a “permanent” customized seating configuration (which can only be reconfigured by a vehicle conversion technician), these drawbacks can be avoided by utilizing the disclosures of the present invention.

DETAILED DESCRIPTION

Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. While the invention will be described in conjunction with the preferred embodiments, the invention is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the invention as defined by the claims. Furthermore, in the detailed description of the present invention, several specific details are set forth in order to provide a thorough understanding of the present invention. However, one of ordinary skill in the art will appreciate that the present invention may be practiced without these specific details. Thus, while the invention is susceptible to embodiment in many different forms, the subsequent description of the present disclosure should be considered as an exemplification of the principles of the invention, and should not be limited to the specific embodiments shown and described herewithin.

As noted above, FIG. 1 depicts a portion of an example vehicle floor 100, including OEM floor 101. OEM floor 101 typically includes a series of ridges 110 formed integrally within OEM floor 101. Compared with an entirely flat surface, ridges 110 in OEM floor 101—and the fact that ridges 110 are integrally formed therein—provide additional stability to the floor of a vehicle in case of impact. Still, ridges 110 create an uneven surface, and since the mounting tiles of the present invention require affixation to a flat, stable surface, vehicle conversion technicians must “fill in the gaps” and reinforce the strength of OEM floor 101, as described hereinbelow.

Referring now to FIGS. 2A-2C, an example mounting tile 10 according to the present invention is shown. Mounting tile 10 is intended for use in mounting a standard vehicle seat, and comprises first tube 11 and second tube 12, both of which are substantially rectangular in cross-sectional shape. That is, each of first tube 11 and second tube 12 include a flat top portion and a flat bottom portion, a first end opposite a second end, and a first longitudinal side opposite a second longitudinal side. Mounting tile 10 further comprises U-shaped channel 14, which has a flat top portion, a first longitudinal side opposite a second longitudinal side, and a first end opposite a second end. U-shaped channel 14 is positioned in between, and affixed to, first tube 11 and second tube 12 parallel to a common longitudinal axis L. Specifically, a longitudinal side of first tube 11 is attached to a first longitudinal side of U-shaped channel 14, while the second longitudinal side of U-shaped channel 14 is attached to a first longitudinal side of second tube 12. Once first tube 11, second tube 12 and U-shaped channel 14 have been positioned adjacently and affixed to one another as shown in FIG. 2A, end caps 13 a are affixed at the respective first and second opposing ends 13 of mounting tile 10.

U-shaped channel 14 comprises apertures 16, 17 and 18 for receiving fastener elements (not shown in FIGS. 2A-2C) which cooperate with a mounting bracket on the bottom of a standard vehicle seat (also not shown in FIGS. 2A-2C). More specifically, apertures 16 and 17 may include weld nuts 16′ and 17′ for telescopically receiving the fastener elements. Weld nuts 16′ and 17′ are not strictly necessary; rather, they assist vehicle conversion technicians by acting as a secondary fastener element (to be used with a primary fastener element, such as a bolt, for example). Positioning weld nuts 16′ and 17′ in alignment with apertures 16 and 17 provides a vehicle conversion technician with greater accessibility to the secondary fastener element, whereas the absence of such weld nuts may require the vehicle conversion technician to position a similar secondary fastener element in a place that is difficult to reach.

Aperture 18 likewise may or may not include a weld nut. In the case where aperture 18 does not include a weld nut, aperture 18 may receive an elongated fastener element, which has a greater length than the fastener elements which cooperate with weld nuts 16′ and 17′. The elongated fastener element protrudes downwardly through mounting tile 10 and through OEM floor 101, as shown in FIG. 10 and further described relative to FIG. 10 hereinbelow. The elongated fastener element is then telescopically received beneath OEM floor 101 by a cooperating threaded fastener element. This affixation beneath OEM floor 101 is believed to provide greater stability to mounting tile 10 and any vehicle seat mounted thereon, compared with the shorter fastener element that cooperate with weld nuts 16′ and 17′.

Referring now to FIGS. 3A-3C, an example mounting tile 20 according to the present invention is shown. Mounting tile 20 is intended for use in mounting cantilevered vehicle seats that are capable of folding to a stowed position, as shown in FIG. 11 and further described relative to FIG. 11 hereinbelow. In such vehicle seats, the seatback can be folded down on top of the seating portion, and the combined seatback/seating portion can be rotated to a stowed, vertical position. Such vehicle seats may include those sold under the trademark FSC FOLDAWAY®, which trademark is owned and used by Freedman Seating Co. of Chicago, Ill., the assignee of the present invention. Whereas standard vehicle seats may be mounted using more than one mounting tile disclosed herein, such folding seats are cantilevered, and may therefore be mounted using only a single mounting tile, for example, mounting tile 20.

Mounting tile 20 comprises first tube 21, second tube 22, third tube 23 and fourth tube 24—each of which is substantially rectangular in cross-sectional shape. That is, each of first tube 21, second tube 22, third tube 23 and fourth tube 24 include a flat top portion and a flat bottom portion, a first end opposite a second end, and a first longitudinal side opposite a second longitudinal side. Mounting tile 20 further comprises U-shaped channels 25 and 26, each of which has a flat top portion, a first longitudinal side opposite a second longitudinal side, and a first end opposite a second end. U-shaped channel 25 is positioned in between, and affixed to, first tube 21 and second tube 22 parallel to a common longitudinal axis L. Likewise, U-shaped channel 26 is positioned in between, and affixed to, third tube 23 and fourth tube 24 parallel to axis L. More specifically, a longitudinal side of first tube 21 is attached to a first longitudinal side of U-shaped channel 25, while the second longitudinal side of U-shaped channel 25 is attached to a first longitudinal side of second tube 22. The second longitudinal side of second tube 22 is positioned adjacent to spaced gap 27, which is positioned adjacent to a first longitudinal side of third tube 23. Likewise, here, the second longitudinal side of third tube 23 is affixed to a first longitudinal side of U-shaped channel 26, while the second, opposite longitudinal side of U-shaped channel 26 is affixed to a longitudinal side of fourth tube 24. Once first tube 21, second tube 22, third tube 23 and fourth tube 24 have been positioned and affixed to U-shaped channels 25 and 26, and second tube 22 and third tube 23 have been positioned and affixed to bracket 32, as shown in FIG. 3A, end caps 28 a are affixed, such as by welding, at the respective first and second opposing ends 28 of mounting tile 20.

As in the case of mounting tile 10, each of U-shaped channels 25 and 26 in this example comprises apertures 36, 37 and 38 for receiving fastener elements (not shown in FIGS. 3A-3C) that protrude from the bottom of vehicle seats. Apertures 36 and 37 may or may not include weld nuts 36′ and 37′, which provide accessibility for vehicle conversion technicians. Weld nuts 36′ and 37′ may telescopically receive the fastener elements from a vehicle seat. In addition, spaced gap 27 includes bracket 32 with its own aperture 33, which may include a weld nut 33′ for telescopically receiving a fastener element from a vehicle seat. Notably, because spaced gap 27 includes bracket 32 with its own aperture 33, apertures 37 are optional in this example of the present invention, because the three rear-facing apertures 38, 33 may be sufficient on their own to prevent forward movement of the vehicle seat, upon any vehicle impact. As with aperture 16 in mounting tile 10, apertures 38 in mounting tile 20 may or may not include weld nuts.

Apertures 38 may receive an elongated fastener element that also protrudes through a mounting bracket affixed to a vehicle seat. For apertures 38 that do not include weld nuts, the elongated fastener elements may be of a greater length than the fastener elements which cooperate with weld nuts 16′ and 17′. The elongated fastener element protrudes downward through mounting tile 20 and through OEM floor 101, as shown in the context of mounting tile 10 a in FIG. 10, and further described relative to FIG. 10 hereinbelow. The elongated fastener element is then telescopically received beneath OEM floor 101 by a cooperating threaded fastener element. This affixation beneath OEM floor 101 is believed to provide greater stability to mounting tile 20 and any vehicle seat mounted thereon, compared with the shorter fastener element that cooperate with weld nuts 36′ and 37′.

Referring to FIG. 4, an example vehicle floor 100 is shown, which includes OEM floor 101. One possible first step in the process of installing the example mounting tiles in a vehicle is to affix layers of bar stock 112 in between ridges 110 of OEM floor 101. Preferably, bar stock 112 is of the same height as ridges 110, so as to create a basis for laying and affixing a flat surface, as described hereinbelow. The affixation of bar stock 112 to OEM floor 101 may be by welding, or by any other suitable means known by those of skill in the art to yield permanent affixation. The affixation of bar stock 112 is not necessary to the present invention, but can be used to provide additional stability for vehicle floor 100.

Referring to FIG. 5, a layer of angle iron 114 is affixed around the perimeter of OEM floor 101. Angle iron 114 affixes and bonds to both OEM floor 101 and to the walls of the vehicle, thereby reinforcing OEM floor 101 to the vehicle walls, and providing additional stability. Again, the means of affixation may be by welding, or by any other suitable means known by those of skill in the art to yield permanent affixation. Once angle iron 114 has been affixed, support struts 116 are affixed laterally across the vehicle at the vehicle's front, the vehicle's rear and the middle of the vehicle. Support struts 116 further reinforce the stability of OEM floor 101 and the vehicle by connecting the affixed angle iron 114 on opposite sides of the vehicle. Together, the ridges 110, optional bar stock 112, support struts 116 and the (horizontal portion of the) angle iron 114 are at substantially the same height, and thereby form a substantially flat primary surface upon which another layer can be placed.

With reference to FIG. 6, a layer of metal plating 118, for example, 14 gauge plate, is affixed to the optional pieces of bar stock 112 and to ridges 110 of OEM floor 101 (each shown in phantom) to create a secondary flooring surface. Metal plating 118 creates the secondary surface as a flat surface on which the example mounting tiles can be affixed. FIG. 7 depicts OEM floor 101 with metal plating 118 affixed thereon, together with mounting tiles 10 and 20. The means of affixation of mounting tiles 10 and 20 to metal plating 118 may be by welding, or by any other suitable means known to those of skill in the art to yield permanent affixation.

Referring to FIG. 8, after mounting tiles 10 and/or 20 have been affixed to metal plating 118, pieces of filler material 120 are laid in between mounting tiles 10 and/or 20 for the purpose of again creating a flat, level, temporary tertiary surface. Filler material 120 may be pieces of wood, metal or any other suitable material for filling in the gaps between the mounting tiles. Preferably, the height of filler material 120 is substantially equivalent to the height of mounting tiles 10 and/or 20, to again impart a substantially flat surface to this tertiary level. Finally, a floor covering 121 is laid down on top of the transitional tertiary surface formed by mounting tiles 10 and/or 20 and filler material 120, to create a final flooring surface. Floor covering 121 is the “floor” upon which passengers of the vehicle will walk after the seats have been installed. As such, floor covering 121 can comprise any material known by those of skill in the art to be used for vehicle flooring, such as plastic, wood, vinyl, carpet or a rubberized material.

FIG. 9 depicts the finished floor of the vehicle, including floor covering 121, and mounting tiles 10 and 20 hidden underneath (as shown in phantom). FIG. 9 further depicts standard vehicle seat 124 mounted on top of mounting tiles 10 a and 10 b, as well as folding vehicle seat 125 mounted on top of mounting tile 20 a. The method of affixing standard vehicle seat 124 to mounting tiles 10 a and 10 b, and of affixing and folding vehicle seat 125 to mounting tile 20 a, is further described hereinbelow with respect to FIGS. 10 and 11.

FIG. 10 depicts a cross-sectional view of the completed vehicle floor and, specifically, of the section of vehicle floor 100 on which mounting tile 10 a (shown in FIG. 9) is affixed. The bottom-most layer depicted in FIG. 10 is OEM floor 101, which includes ridge 110. Immediately above OEM floor 101 is a piece of optional bar stock 112, which is covered by metal plating 118. Mounting tile 10 a is affixed on top of metal plating 118, and the sections behind and in front of mounting tile 10 a are filled with filler material 120. Finally, floor covering 121 is laid on top of mounting tile 10 a and filler material 120.

Standard vehicle seat 124 (shown in FIG. 9) includes leg element 130, for use with mounting tile 10 a, and leg element 131, for use with mounting tile 10 b, with leg elements 130, 131 protruding downward from standard vehicle seat 124. Each of leg elements 130, 131 is integrally attached to a mounting bracket, for example, mounting bracket 132, which may be of substantially the same surface area as mounting tile 10 a. Leg elements 130, 131 are of a substantially rectangular shape, and remain open on one side to enable the attachment of fastener elements 136, 137 and 138. Fastener element 136 is telescopically received by and cooperates with weld nut 16 a, which is affixed to aperture 16 in mounting tile 10 a. Likewise, fastener element 137 is telescopically received by and cooperates with weld nut 17 a, which is affixed to aperture 17 in mounting tile 10 a. As shown in FIG. 10, unlike fastener elements 136 and 137, which do not protrude beyond the layer of metal plating 118, fastener element 138 protrudes downward through mounting tile 10 a, through metal plating 118, and through OEM floor 101, where it is telescopically received by and cooperates with nut 18 a. Since leg element 132 is the rear-most leg element of standard vehicle seat 124, this affixation of leg element 132 through the bottom of OEM floor 101 creates additional stability for restraining standard vehicle seat 124 in its position, in the case of a forward-moving vehicle impact. Alternatively, aperture 18 of mounting tile 10 a may also include weld nut 18′, in which case fastener element 138 does not protrude downwardly through the entirety of mounting tile 10 a.

FIG. 11 depicts a cross-sectional view of the completed vehicle floor and, specifically, of the section of vehicle floor 100 on which mounting tile 20 a (shown in FIG. 9) is affixed. The bottom-most layer depicted in FIG. 10 is OEM floor 101, which includes ridge 110. Immediately above OEM floor 101 are pieces of optional bar stock 112, which are covered by metal plating 118. Mounting tile 20 a is affixed on top of metal plating 118, and the sections to the sides of mounting tile 20 a are filled with filler material 120. Finally, floor covering 121 is laid on top of mounting tile 20 a and filler material 120.

Folding vehicle seat 125 (shown in FIG. 9) is cantilevered, and thus includes only a single leg element 140, for use with mounting tile 20 a. Leg element 140 protrudes downward from folding vehicle seat 125, and supports the weight of folding vehicle seat 125 via cantilever 142. The bottom of leg element 140 is integrally attached to mounting bracket 141, which may be of substantially the same surface area as mounting tile 20 a. As shown in FIG. 11, fastener elements 136 are telescopically received by and cooperate with weld nuts 36 a, 36 b, which are affixed to apertures 36 in mounting tile 20 a. Likewise, fastener element 133 is telescopically received by and cooperates with weld nut 33 a, which is affixed to aperture 33 in mounting tile 20 a. While not shown in FIG. 11, additional fastener elements are telescopically received by and cooperate with weld nuts 37′ (shown in FIG. 3B). Further, as described above with respect to FIG. 10, to provide additional stability in the case of a forward-moving vehicle impact, additional fastener elements 140, 142 may protrude through apertures 38 (also shown in FIG. 3B), downward through mounting tile 20 a, through metal plating 118, and through OEM floor 101, where they are telescopically received by and cooperate with nuts 40, 42 underneath OEM floor 101. Alternatively, apertures 38 of mounting tile 20 a may each also include a weld nut, in which case the fastener elements 140, 142 cooperate with the weld nuts, and do not protrude downwardly past metal plating 118.

The foregoing description and drawings merely explain and illustrate the invention, and the invention is not so limited, as those skilled in the art who have the disclosure before them will be able to make modifications and variations therein without departing from the scope of the invention.
